With Europe’s biggest trade show set to open its doors in Berlin later this week, signaling a new tech refresh cycle in time for the back-to-school shopping season, Acer got things rolling with a round of announcements this morning. Among them is a quartet of all-in-one desktops -- one of which runs Android instead of Windows.

The DA241Hl is "designed to offer users the same familiar experience as with tablets and smartphones," according to the company. Detailed specifications are rather scarce at the moment but we know the device features a 24-inch 1080p display, a quad-core Tegra 3 processor from Nvidia and Android Jelly Bean 4.2. Users will have access to the Google Play Store for application downloads, and thanks to Android’s multi-user accounts feature, up to five people can customize their experience with individual settings and apps.

Other features include MHL connectivity, which means the all-in-one can double as a monitor for smartphones or a Windows PC hooked up via HDMI, complete with two-point touch support.

The other three all-in-one desktops announced today have a full HD 23-inch touch display, Windows 8 and the latest Intel or AMD CPUs. Specifically, the Aspire U5-610 comes with your choice of Intel Haswell processors, along with an Nvidia GeForce GTX 760M GPU and up to 16GB of RAM for €1,129 and up. The Aspire Z3-105 and Z3-610 both start at €799, the first featuring AMD's latest A series quad-core CPUs with Radeon graphics, while the latter runs an Intel Haswell processor with your choice of Intel graphics or a discrete Nvidia GPU.

Other IFA 2013 announcements from Acer

Aside from its Android equipped all-in-one desktop and 4K recording Liquid S2 smartphone, Acer has a few other products lined up for IFA 2013. Among them are refreshed Acer Aspire R7 ad E1 laptops, a new Iconia A3 tablet, and a 27-inch monitor featuring multitouch and a 2,560x1,440 pixels resolution.

On the laptop front Acer is basically upgrading to Haswell while throwing a stylus into the mix for the Star Trek-esque R7, which arrives in Europe next quarter for €999. The low-budget Aspire E1 will be available in mid-October with an optional ten-point multitouch display and a €399 starting price.

Meanwhile, the 10.1-inch Iconia A3 tablet is a step up from the A1 announced earlier this year, running Android Jelly Bean on a quad-core 1.2GHz Cortex A7 processor and a 1,280 x 800 display. The 16GB Wi-Fi only version will cost €249 and arrive in Europe in early October, while the 3G version will cost €299. A 32GB variant is also available and both support microSD cards to expand storage.
